Six things for PR pros to know Wednesday morning

1. Twitter will suspend the accounts of users who post graphic images of the apparent beheading of American journalist James Foley by members of the Islamic State of Iraq and Syria. Representatives from the State and Defense departments reached out to the microblogging platform on Tuesday to ask it to take "appropriate action consistent with stated usage policies," according to The Washington Post.

Foley had been covering the conflict in Syria for US-based news service GlobalPost. ISIS threatened to kill another American journalist if the US does not call off airstrikes against the group in Iraq.

We have been and are actively suspending accounts as we discover them related to this graphic imagery. Thank you https://t.co/jaYQBKVbBF

Twitter also said on Tuesday that it will remove photos of the deceased upon the request of family members, nearly one week after Robin Williams’ daughter quit the platform after she was harassed with photoshopped images of her father.

2. David Plouffe’s new job at Uber won’t be that different from some of his work in 2008 during Barack Obama’s first campaign for president. He’ll take the fight to an establishment candidate — in this case, taxis — on a state-by-state basis and try to convince a base of young, urban professionals that they should support his boss, according to Politico. Plouffe will join Uber next month as SVP for policy and strategy, overseeing all communications, branding, and public-policy initiatives.

3. News, TV and movie clips, and advertisements could soon appear — and then disappear — on Snapchat, according to The Wall Street Journal, which reported the service is in talks with media and advertising companies about launching a service called Snapchat Discovery.

4. Ferguson, Missouri, was mostly peaceful overnight, with only limited violence taking place alongside protests. Attorney General Eric Holder will visit the St. Louis suburb on Wednesday to determine the federal government’s response to a week-plus of unrest after the shooting of unarmed black teenager Michael Brown last Saturday.

5. Walgreens pushed out two executives, one its CFO, after a billion-dollar forecasting error for its Medicare-related business, according to The Wall Street Journal. The company said finance chief Wade Miquelon was stepping down earlier this month.

6. Former NFL linebacker Tim Shaw took the Ice Bucket Challenge, but also announced he is fighting ALS, in a video released on Tuesday. Shaw, who played for the Tennessee Titans from 2010 to 2012, asked members of his former team and his alma mater, Penn State, to take the challenge. The initiative has prompted $15 million in donations for ALS research and more than 8 million mentions in tweets.
